3 pairs of shoes cost 189

Step-by-step explanation:

Oh yes it's quite simple but sort of difficult to explain, I'll try the best I can though!

in "C(x)" what ever is in the ( ) is the x value, so where they give you "C(3)" that means x=3. And since in this x represents number of shoes, that means the cost of three shoes is $189.

Hope this helps! If you have any questions about my answer feel free to ask. Stay safe!
